Abstract: Feeding behavior of Aratinga aurea (Psittacidae) in southwestern Minas Gerais State, Brazil. This research was carried out from August 1995 to August 1998. The objective is obtain data on feeding behavior of the Peach-fronted Parakeet (Aratinga aurea) in southwestern Minas Gerais State. Thirty-three plant species were eaten by A. aurea. Hyptis suaveolens (Lamiaceae) and Psidium guajava (Myrtaceae) were the most consumed. Aratinga aurea fed on flowers, fruit pulp but seeds were the most consumed item. The use of leaves as food was recorded only for Pyrus communis (Rosaceae), on a single feeding bout. From 33 species eaten, parakeets used seeds from 18 species, fruit pulp from seven and flowers from 12 species. The methods used to obtain food varied according to the size of plant species, as well as the morphology. Generally, it was possible to define three basic strategies: (1) the bird pecks the food without ripping it from the branch, (2) the birds plucks off the food with its beak and grinds it, (3) the bird plucks off the food with its beak, grabs it using its foot and only then starts to eat it. There was statistically significant variation of the methods used in relation to the food item. The flock size during feeding is highly variable. Flock size varied from one individual eating alone to 20 individuals at the same site. Records of flocks of one or two birds were mostly made during breeding period.
